Three actors could play Cher after the singer revealed that an inventive musical based on her life was being developed for the stage.

Earlier this week, the 66-year-old singer took to Twitter to reveal that she was working with producers to write a musical that uses her songs to tell her life story. While the planned timescale remains unclear, the singer said that the production is being developed with Broadway in mind.

She added: "Its VERY SLOW PROCESS! Been working on it quite a while now [sic]."

Currently, the musical focuses on three stages of the singer's life, with a different actor playing her in each part. One actor will portray her before she met Sonny Bono; another after the couple separated through to her Believe tour in 1999, and a third will play the singer in the present day. "They all 3 talk 2 each other &Sing 2gether," Cher tweeted.

The singer also stressed her own involvement: "I'm help. 2 write cause I was there and know stories that no1 knows but me."
